Cable Color Requirements for Distribution Boxes
The IEC 60446 standard, “Basic and Safety Principles for Man-Machine Interface, Marking, and Identification,” establishes global guidelines for identifying electrical equipment terminals, conductors, and wiring colors. The standard electrical wire color code mandated by the National Electrical Code (NEC) is a critical safety system for licensed electricians. For typical building AC circuits (commonly up to 600 volts nominal), the NEC specifies identification rules for grounded conductors (neutral), requirements. Primary power distribution cable shall be single conductor stranded copper, with ethylene propylene rubber (EPR) insulation rated 15kV, 90 degrees C, 133 percent insulation level, having a 5 mil thick minimum tape shield with 12-1/2 percent minimum overlap, and polyvinyl chloride (PVC) jacket. WARNING: Please be aware that the table below is a guide; a wire should never be identified by color alone. Wire color helps identify intent, not actual condition. A generator system designer and service technician installing and maintaining generator equipment must know the current NEC color and sizing codes or cables within the system.
